Interpretability

Train interpretable classification models and interpret complex classification models

Use inherently interpretable classification models, such as linear models, decision trees, and generalized additive models, or use interpretability features to interpret complex classification models that are not inherently interpretable.

To learn how to interpret classification models, see Interpret Machine Learning Models.
